Specification of Letters Patent.

Application filed August 1 2, 1913. Serial no. degree.

To all whom it may concern:

scribed and claimed.

Be it known that we, JosErH S. KAu'rMAN and ISAAC KAUFMAN, citizens of the United. States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Bottle-Caps, of whichthe following is a specification.

This invention relates to bottle caps; and it has for its primary. object the provision of a device of this character. which will serve to completely close the upper end of.

operation of applying the cap to or removing the same from the neck of the bottle as the occasion may demand.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be In the .accompanying drawings:Figure 1 is a perspective view, illustrating the initial operation of'applying.the cap to the bottle neck; Fig. 2 is a similar view showing the cap in its-applied position;'Fig. 3 is an edge view thereof; Fig. 4 is a horizontal section on the line 44 of Fig. it; Fig. 5 is a plan .view of a portion of the blank from which the cap is formed; and Fig. 6

is a vertical section through a portion of the bottle, showingvthe application of the cap thereto. y

The cap 1 herein illustrated is designed particularly for use upon milk bottles or the like for sealing the neck in such manner as to minimize the possibility of the elements entering the bottle .and mixing w1th, the

original contents thereof.' The cap may be tic material having a uniform thickness throughout and stamped or otherwise suitablyformed so as to provide amain crown 2 which overlies the' neck and which is extended into an elastic concavo-convex rim or flange 3. The material in the flange formv ing portion 3 thereof is provided at spaced intervals with extensions 4 having angular hereinafter deedges 5 extending opposite directions and gradually merglng into the lower edges of adjacent portions of the flange or rim 3.

The extenslons {i are designed to give to the or flange 3 an extra fullness of materlal so that under the inherent elasticity of the metal, the flange is expansible and.

may be readily sprung over the head 6 of the bottle 7 herein shown whereby to eflectually embrace the bead and to form a seal around theneck of the bottle to minimize the possibility of outside elements entering the bottleand mixing with the contents thereof. Each portion 4 isprovided with a weakened line 8 which terminates directly at the juncture of the flange or rim 3 with the crown 2. Each extension is thus formed so that it may be folded on itself as shown particularly in Fig. 4:, providing substanadapted for relative separation during'the operation of forcing the flange 3 over the bead 6 of the bottle neck.

The constructiom of the device is such that while the operation of applying the device to the bottle is greatly facilitated the corners 10 of the extension 4 are disposed in positions normallly whereby to permit of their being engaged by the fingers of the hand and pressure of the hand applied thereto in an upper direction during the operation. of removing the cap from the bottle.

From the foregoing description, takenin connection with the accompanying draw rate'nateri Jan. '5, 1.915.

.tially accordion like folds '9, which are ings, the construction andoperation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportlon and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as claimed.

Having thus described our invention, what we claim is A bottle cap constructed of of sheet material provided with a crown having a depending normally concavo-convex'fiange provided with a pair. of spaced extensions, each of said extensions being weakened on an uneven number of lines which are disposed in converging relation in the direction of the edge'of the crown and which extend throughoutthe' width of the flange, each of said extensions being a single blank 7 the operation of removing the cap from the bottle or applying the same thereto.

In testimony whereof We afiix our signatures in presence of two Witnesses.
